There are two versions included this pattern, Fingering yarn and size US 6 needle, or worsted yarn and size US 10 needle. Other variations will work as well, just play around and use the needle for the largest weight yarn you are including.
The thinner yarns will be lacier, supported by the thicker ones.

This is designed to utilize remnants and leftover partial balls, so you have infinite possibilities. Post your results and link to pattern so others can benefit from your diverse results!
? Enjoy!?
